Sentinel-2: Cloud Probability

The S2 cloud probability is created with the [sentinel2-cloud-detector](https://github.com/sentinel-hub/sentinel2-cloud-detector) library (using [LightGBM](https://github.com/microsoft/LightGBM)). All bands are upsampled using bilinear interpolation to 10m resolution before the gradient boost base algorithm is applied. The resulting `0..1` floating point probability is scaled to `0..100` and stored as an UINT8. Areas missing any or all of the bands are masked out. Higher values are more likely t
